Feature #2077
Updated by Victor Julien about 7 years ago
It would be very useful to have the following buffers from the HTTP Header: http_referer http_version http_accept http_accept_language http_accept_encoding http_connection http_content_length http_content_type It would also be very useful to be able to negate on buffers without having to access the http_header buffer. Often we use lines such as content:!"Referer|3a "content:!Referer|3a 20|"; http_header; to indicate that http_referer is not present in the request It would be useful to be able to say !http_referer; or !http_user_agent; essentially just saying that the buffer has no contents or doesn't exist for this request.
